What is the largest fuel tank that you make?

I need this for a YS 140DZ in a pattern plane. I want to install it on the CG. Could I use 2 12oz tanks, next to each other, feeding fuel on a Y lead?

Thank you

At the moment, the 12oz is the largest tank.

I have in the past connected two 8oz tanks in parallel with a Y connection. That worked well. No reason a pair of 12oz tanks would not work just as well.

However, the YS140 is a pressure/return fuel system like the rest of the YS engines ...... is it not?

In that case, bypass fuel from the regulator has to return the fuel tank during operation.

The bubble-jett tank can not be utilized with such a fuel system, since the fuel and "pressure" sides are isolated from eachother by a bladder. The return fuel would not return to the fuel supply.
